Vulnerability Title
net: libwx: remove duplicate page_pool_put_full_page()
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: net: libwx: remove duplicate page_pool_put_full_page() page_pool_put_full_page() should only be invoked when freeing Rx buffers or building a skb if the size is too short. At other times, the pages need to be reused. So remove the redundant page put. In the original code, double free pages cause kernel panic: [ 876.949834] __irq_exit_rcu+0xc7/0x130 [ 876.949836] common_interrupt+0xb8/0xd0 [ 876.949838] </IRQ> [ 876.949838] <TASK> [ 876.949840] asm_common_interrupt+0x22/0x40 [ 876.949841] RIP: 0010:cpuidle_enter_state+0xc2/0x420 [ 876.949843] Code: 00 00 e8 d1 1d 5e ff e8 ac f0 ff ff 49 89 c5 0f 1f 44 00 00 31 ff e8 cd fc 5c ff 45 84 ff 0f 85 40 02 00 00 fb 0f 1f 44 00 00 <45> 85 f6 0f 88 84 01 00 00 49 63 d6 48 8d 04 52 48 8d 04 82 49 8d [ 876.949844] RSP: 0018:ffffaa7340267e78 EFLAGS: 00000246 [ 876.949845] RAX: ffff9e3f135be000 RBX: 0000000000000002 RCX: 0000000000000000 [ 876.949846] RDX: 000000cc2dc4cb7c RSI: ffffffff89ee49ae RDI: ffffffff89ef9f9e [ 876.949847] RBP: ffff9e378f940800 R08: 0000000000000002 R09: 00000000000000ed [ 876.949848] R10: 000000000000afc8 R11: ffff9e3e9e5a9b6c R12: ffffffff8a6d8580 [ 876.949849] R13: 000000cc2dc4cb7c R14: 0000000000000002 R15: 0000000000000000 [ 876.949852] ? cpuidle_enter_state+0xb3/0x420 [ 876.949855] cpuidle_enter+0x29/0x40 [ 876.949857] cpuidle_idle_call+0xfd/0x170 [ 876.949859] do_idle+0x7a/0xc0 [ 876.949861] cpu_startup_entry+0x25/0x30 [ 876.949862] start_secondary+0x117/0x140 [ 876.949864] common_startup_64+0x13e/0x148 [ 876.949867] </TASK> [ 876.949868] ---[ end trace 0000000000000000 ]--- [ 876.949869] ------------[ cut here ]------------ [ 876.949870] list_del corruption, ffffead40445a348->next is NULL [ 876.949873] WARNING: CPU: 14 PID: 0 at lib/list_debug.c:52 __list_del_entry_valid_or_report+0x67/0x120 [ 876.949875] Modules linked in: snd_hrtimer(E) bnep(E) binfmt_misc(E) amdgpu(E) squashfs(E) vfat(E) loop(E) fat(E) amd_atl(E) snd_hda_codec_realtek(E) intel_rapl_msr(E) snd_hda_codec_generic(E) intel_rapl_common(E) snd_hda_scodec_component(E) snd_hda_codec_hdmi(E) snd_hda_intel(E) edac_mce_amd(E) snd_intel_dspcfg(E) snd_hda_codec(E) snd_hda_core(E) amdxcp(E) kvm_amd(E) snd_hwdep(E) gpu_sched(E) drm_panel_backlight_quirks(E) cec(E) snd_pcm(E) drm_buddy(E) snd_seq_dummy(E) drm_ttm_helper(E) btusb(E) kvm(E) snd_seq_oss(E) btrtl(E) ttm(E) btintel(E) snd_seq_midi(E) btbcm(E) drm_exec(E) snd_seq_midi_event(E) i2c_algo_bit(E) snd_rawmidi(E) bluetooth(E) drm_suballoc_helper(E) irqbypass(E) snd_seq(E) ghash_clmulni_intel(E) sha512_ssse3(E) drm_display_helper(E) aesni_intel(E) snd_seq_device(E) rfkill(E) snd_timer(E) gf128mul(E) drm_client_lib(E) drm_kms_helper(E) snd(E) i2c_piix4(E) joydev(E) soundcore(E) wmi_bmof(E) ccp(E) k10temp(E) i2c_smbus(E) gpio_amdpt(E) i2c_designware_platform(E) gpio_generic(E) sg(E) [ 876.949914] i2c_designware_core(E) sch_fq_codel(E) parport_pc(E) drm(E) ppdev(E) lp(E) parport(E) fuse(E) nfnetlink(E) ip_tables(E) ext4 crc16 mbcache jbd2 sd_mod sfp mdio_i2c i2c_core txgbe ahci ngbe pcs_xpcs libahci libwx r8169 phylink libata realtek ptp pps_core video wmi [ 876.949933] CPU: 14 UID: 0 PID: 0 Comm: swapper/14 Kdump: loaded Tainted: G W E 6.16.0-rc2+ #20 PREEMPT(voluntary) [ 876.949935] Tainted: [W]=WARN, [E]=UNSIGNED_MODULE [ 876.949936] Hardware name: Micro-Star International Co., Ltd.
